You've got the symptoms of a weak battery. Was the battery sitting around in the bike for a year too? If it was it's probably for the bin. They can show 12V and they can even take a full charge but when you hit the starter the voltage drops from a weak cell or two. You could jump it off a car battery and see if it turns over just make sure the car is off. Do you know the history of the bike or the reason why it was parked up?
